What is a good way to benchmark test a GPU in Linux?
Edit: I was able to run some benchmark tests, so I don't need help with this anymore, but after running the tests, I'm pretty sure my computer is having hardware issues. I don't really have any other options, though, so I just have to deal with it.
The computer I was using stopped working and I had to switch to a different computer but despite having a significantly better GPU, games are performing only slightly better. I want to benchmark test the GPU to see if it's a potential hardware problem or if something else is causing a bottleneck.
I use the unigine benchmarks sometimes. unigine-heaven and unigine-superposition (which btw is just cool to watch in my opinion). They provide linux packages here https://benchmark.unigine.com/ , check your distributions repos too though, some include these too though it's rare. They are not open source, but games usually aren't either.
The phoronix one that someone else posted also looks cool, I'll have to try that one out next time I need something like this.
I tried to download unigine but I can't seem to figure out how to download it. I'm using Linux Mint and the only download option seems to be a .run file which doesn't seem to be executable in Mint. I also don't know how to look through the repositories and when I tried to install "unigine-heaven" in apt, it told me it couldn't find it in the repositories. So unless it's called something else when you install it through apt, I don't know how to download it.
Also, I did look into Phoronix but it only mentions that it benchmarks CPUs and not GPUs.
Do you know what the browser test is called or how to run it?
I didn't run glxgears and I did run glmark2 yesterday but I stopped it half way through. If I remember correctly, the frame rates from the test ranged from 80 to over 1000 fps depending on the test but I have no idea if that's good for the GPU or bad because I don't remember the results I got on my old computer. If someone knows GPUs well enough, my old GPU was an intel HD Graphics 3000 and the GPU in this computer is an AMD Radeon R2 Graphics.
Also, I looked into Phoronix but it looks like it just benchmarks CPUs.
I did find it but it is just a VSYNC test thing. Not sure how to diagnose these things. The only time I had major issues was when I installed the wrong drivers, so user error. Maybe the distro you're using has an IRC or Matrix chat room that would be willing to help out?
Honestly your best bet is probably to use a game with a built-in benchmark over Steam. That way you get numbers that are somewhat comparable to the ones from public sources (game review sites/videos).
I don't know why there isn't a proper tool like 3DMark for Linux systems.
When you say "built-in benchmark over Steam" what does that mean? If that is a common thing, I have a steam account but I've never really used it before as I get pretty much all of my games from itch.
Ok, I tried that but is it just supposed to display a triangle? It also didn't have a GUI, is that only in the MacOS version of the app or am I supposed to run the .py file? If I'm to run the .py file, that is something I don't know how to do.
There's a bunch of benchmarks you can run apart from the triangle, like Furmark which render a more complex scene. I've only used the shell scripts, no idea what the python script does.
